Extracted text: Suppose that you are interested in the effect of workout on Health and plan to estimate the following model, Health = a + ßworkout + u where Health is a health score on a scale of 1 to 10. The smaller the number, the better one's health is. workout is the number of times one works out per week. One component if u is a person's health consciousness. OLS estimator will most likely Overestimate the impact of workout on Health Underestimate the impact of workout on Health Efficiently estimate the impact of workout on Health Lead to a biased estimate of the impact of workout on Health but the direction of bias is unknown.
